View in English SwiftUI helps you build great-looking apps across all Apple platforms with the power of Swift — and surprisingly little code. You can bring even better experiences to everyone, on any Apple device, using just one set of tools and APIs. Discover what’s new in SwiftUI Dive into the latest key features and capabilities of the Swift language. New to SwiftUI development? Get started with our SwiftUI Pathway, an easy-to-navigate collection of resources to get started. Get to know SwiftUI Declarative syntax Write the results, not the instructions SwiftUI uses a declarative syntax, so you can simply state what your user interface should do. For example, you can write that you want a list of items consisting of text fields, then describe alignment, font, and color for each field. Your code is simpler and easier to read than ever before, saving you time and maintenance. This declarative style even applies to complex concepts like animation. Easily add animation to almost any control and choose a collection of ready-to-use effects with only a few lines of code. At runtime, the system handles all of the steps needed to create a smooth movement, even dealing with user interaction and state changes mid-animation. With animation this easy, you’ll be looking for new ways to make your app come alive. SwiftUI essentials Easy integration Adopt SwiftUI at your own pace

SwiftUI is designed to work alongside UIKit and AppKit, so you can adopt it incrementally in your existing apps. When it’s time to construct a new part of your user interface or rebuild an existing one, you can use SwiftUI while keeping the rest of your codebase the same. Alternatively, if you’re building a new SwiftUI app and want to use an interface element that isn’t offered, you can mix and match with UIKit and AppKit to get the best of all worlds. Iterate quickly and preview while you work With Xcode previews, you can make changes to your app’s views in code, and see the results of those changes quickly in the preview canvas. Add previews to your SwiftUI views using the preview macro. Then configure how you want your previews to display using Xcode’s preview canvas, or programmatically in code. When you select the live or interactive preview option, your view appears and interacts just like it would on a device or simulator. And in select mode, the preview displays a snapshot of your view so you can interact with your view’s UI elements in the canvas. Selecting a control in the preview highlights the corresponding line of code in the source editor. Finally, you can adjust device settings to control how a preview displays, including in Dark Mode, landscape orientation, or different sized text.
